they are having a lot of issues with the law, i dont know why you are still using bittrex, a lot of exchanges are being shutted down and they are lossing a lot of money, but bitcoin keeps rising, i dont understand the real purpose of this, but of course that bittrex needs a financial legal advice as soon as possible because a lot of people are not able to withdraw their money from there, and this is very shady and makes bad advertising about theirselves.
but they are still one of the best exchanges of cryptos that are still online.
For the important reason, the bittrex requirements is very complicated right now. The more daily trade volume on the bittrex gets move into the another exchange site just like binance.
My friend got ban due to the unknown reason and he has verified his own account. That doesn't make sense the bittrex just ban with a security reason rather than gives an actual reason about that, I move toward another exchange site.
I'm not use it again right now. But i just think about the bittrex based on the US exchange site which makes them to strict the users caused by the regulation.
